Consistent tamping = consistent extractions. Choose the right size for your basket (51/53/54/58/58.5 mm). All Coffee Nerd tampers use a 304 stainless base for reliable weight and a level surface. For the best results, match your tamper to your machine’s basket size (e.g., Breville/Sage 54 mm; E61/Gaggia 58 mm), and pair with a Distributor to even out the puck before tamping.
